  1. TV trick only works on old cathode ray tube (CRT) TVs – the ones with the massive bit at the back – because they work on the principle of an electron gun (sounds cool, I know, but it's actually really quite boring and complicated…) which can be manipulated with a magnetic field. If you tried it with modern-day LCD or plasma TVs it wouldn't work, as they work on the principle of electric charge and not anything to do with electrons, hence a magnetic field would do nothing to the picture.
